Hi. I'm new to this forum. I’ve always wanted to live longer, ever since I was a kid. I'm still pretty young but I recently decided to go on a calorie restricted diet. The thing is that I’m not sure how to do that and I could really use some help.
I’ve been relatively skinny most of my life. My BMI is around 19 and has been around that since I was a 15-16. I suffer from Hashimoto’s (autoimmune hypothyroidism) and have recently had to eat relatively little to maintain my weight and look and feel like my normal self. I work out 6-8 hours per week of relatively intense exercise and eat around 1600-1800 calories a day. I try to eat nutritious food.
I’m sensitive to fiber so I have to restrict my vegetable intake. Eating more than 20 g of fiber per day makes me very gassy and prevents nutrients from getting absorbed. I try to eat nutritious foods that are low in fiber.
The way I understand this diet is that people cut calories to the point where their metabolism slows down and their bodies barely get enough calories to survive. But their diet is rich enough to provide all the necessary nutrients by eating lots of vegetables and fiber. What do I need to do if my metabolism is already crawling. I’m on medication so I’m not currently hypo but my metabolism is very slow compared to the way it was before I had thyroid issues. My thyroid hormones are currently in the normal range but they're very close to hypo (my FT3 is at the low end of the healthy range and my FT4 is not that far above it). Do I need to slow down my metabolism more? Do I need to eat less if my BMI is already relatively low? How can I do this diet if I can’t eat fiber.
